SUPPORT FOR SEWING-MAGHINE MOTORS.

Application filed May 27, 1920. Serial No. 384,738.

To all whom it may concern:

Be it known that I, MARvIN L. Norms, a citizen of the United States,residing at Fort Wayne, county of Allen, State of Indiana, have inventedcertain new and useful Improvements in Supports for Sewing- MachineMotors, of which the following is a specification.

My invention relates to an improved means for supporting the drivingmot'orof a sewing machine in either of two positions. The object of myinvention is to provide an improved supporting bracket so arranged thatit will support the motor in either of two positions, an operativeposition, in which the driving wheel of the motor will be in drivingrelation with the fly-wheel of the sewing machine, and an inoperativeposition, in which the motor will occupy less than it does in theoperative position, so that the machine may be provided with a cover ofas small dimensions as possible.

The particular features of novelty which characterize my invention willbe pointed out with particularity in the claims annexed to and forming apart of this specification.

M invention will be more readily understood by referring to theaccompanying drawings in which Fig. 1 is an end view of a sewing machineprovided with a motor mounted in accordance with my invention; Fig. 2 isa front elevation of the same; Fig. 3 is also a front elevation, bitishows the motor moved into the inoperative position; Fig. 4; is afront view in detail of my motorsupporting bracket; Fig. 5 is a sideviewof the same, and Fig. 6 is also a front view, but shows themotor-supporting plate turned into the inoperative position.

Referring to the drawings, 1 indicates the sewing machine pillar whichis provided with the usual horizontal arm and which supports thefly-wheel 2 and the mechanism for transmitting motion from the fly-wheelto the needle bar. An electric motor 3, whose shaft is provided with adriving wheel 4:, w which in turn is chine pillar.

This bracket 5 forms the novel support of my invention and comprises twopivots bolted to the sewing maa supporting plate 6,

space with relation: to tlie sewing 11130111116 is mounted upon thebracket 5.

1-1 and 14. Pivot 11 is in the form of a hinge 14; has a substantiallyhorizontal axis substantlally at right angles to the pivot 11.

A resilient member or spring 12 tends to bias the motor toward thesewing machine. When the motor is in an operative position, as shown inFig. 2, the motor shaft is substantially horizontal and the drivingWheel engages the fly-wheel 2 of the sewing machine, but when the motoris in an inoperative position the motor is substantially vertical anddriving wheel & is out of engagement with the fly-wheel, as shown inFig. 3. 2 Referring to Figs. 4. to 6 of the drawing, it will be seenthat the bracket 5 comprises bolted to the sewing machine pillar, whichcarries pivotally mounted thereon at 1%, .as plainly shown in thedrawing, a plate 7 provided at each end with a projecting arm 8, and amotor-supporting plate 9 similarl provided with projections 10 at eachend which are hinged to the projections 8 of plate 7 by means of ahinge-pin 11, surrounding which is the spring 12, one end of whichengages one of the projections on plate 7 and the other engages aprojection on plate 9 in such a manner as to give to the plate 9 a biastoward the stop lugs 13 formed on the side arm 8 of plate 7.

7, It will be seenby referring to Fig. 1, tlciat the motor-driving wheelis held against the fly-wheel 2 by the pressure of the spring 12 of thebracket, but when the motor s turned to the position shown in Fig. 3,were it not for the stops 13, on the arms 8 of plate 7, the motor wouldswing around into contact with the pillar of the sewing machine.

The rigidly mounted plate 6 is provided with a lug 15 which projectstherefrom in two planes and serves to limit the rotation of thesupporting plate 7 on its pivot either to the left to properly positionthe motor pinion with relation to the driving wheel, or to the right tothe inoperative position as shown in Figs. 3 and 6.

I have described my invention as embodied in what is now considered thepreferred form, in accordance with the patent statutes, but it will beunderstood that the arrangement may be modified, and I therein and hasan axis substantiallyparallel to the shaft of the motor 3. Pivot adaptedto be rigidly.

fore aim to cover all such modifications in the appended claims, as comewithin the scope of my invention.-

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is,

1.- A motor-supporting bracket adapted to support a motor in either oftwo positions comprising in combination, a pivotally mounted plateprovided with a projecting arm at each end, a motor-supporting platealso provided with a projecting arm at each end, a hinge-pin connectionbetween the projecting arms of said plates, a stop-lug on I each of theprojecting arms of. said first mentioned plate, and a spring so arrangedas to bias said motor-supporting plate toward said stop-lugs. i

2. A' motor-supporting bracket adapted to support a motor in either oftwo positions comprising in combination, a member adapted to be rigidlymounted, a plate pivotally mounted on said member and provided with aprojecting arm at each end, a motor-sup porting plate also rovided witha projectmg arm at each en a hinge-pin connection between the projectingarms of said plates,

a stop-lug on each of the projecting arms of said first mentioned plate,and a spring so arrangedas to bias said motor-supporting plate towardsaid stop-lugs.

3. A motor-supporting bracket adapted to support a motor in either oftwo positions comprising in combination, a member ada ted to be rigidlymounted, a plate pivota ly mounted on said member and provided withmounted plate, a stop-lug on each of the projecting arms of saidpivotally mounted plae, and a spring so arranged as to bias saistop-lugs. v

In witness whereof, I have hereunto set my hand this twenty-fourth dayof May,

MARVIN L. NORRIS.
